Sun Metals Corp. Closes Acquistion of Lorraine Project

The Lorraine project is host to a precious metal enriched, alkalic porphyry copper system. Examples of deposits with this style of mineralization in British Columbia include Galore Creek, New Afton, and Mount Polley.

"Having full ownership of Lorraine is an important step forward as we build a quality portfolio of high-grade copper-gold exploration projects at Sun Metals. The Company now controls two high-grade copper-gold projects in the area, both with excellent exploration potential," stated Steve Robertson, Sun Metals' President and CEO.

Pursuant to the terms of the acquisition, Sun Metals has issued 4,633,440 common shares of the Company to Teck with a fair market value of $500,000 based on the Company's 20-day VWAP of $0.108 per share. The common shares are subject to a statutory four month and one day hold, expiring March 26, 2021.

The common share issuance, together with the 13,039,546 common shares currently held by Teck, will result in Teck holding 17,672,986 common shares or approximately 10.29% of Sun Metals outstanding shares on a non-diluted basis. Teck may determine to increase or decrease its holdings in Sun Metals depending on market conditions and any other relevant factors. A copy of Teck's early warning report may be obtained from Chris Stannell at 604 699 4368.

Pursuant to the terms of the acquisition, Teck has also retained a 1.0% NSR royalty on all claims that are not already burdened by a royalty and a 0.25% NSR royalty on all claims that are subject to existing royalties. In addition, Sun Metals will make the following future payments to Teck in either cash or common shares of the Company as follows:

• $500,000 payable on November 25, 2021; and
• $500,000 payable on November 25, 2022.

Sun Metals will also make milestone payments to Teck in either cash or common shares of the Company as follows:

• $500,000 upon a Preliminary Economic Assessment;
• $2,000,000 upon a Feasibility Study; and
• $5,000,000 upon a construction decision.

If Sun Metals sells or options all or a portion of the property to a third party at any time during a 60-month period commencing from the date of the acquisition agreement, Sun Metals will pay to Teck 20% of the sale proceeds, net of exploration expenses incurred on the property by Sun Metals following closing.

Lorraine Project Overview

The Upper Main, Lower Main and Bishop zones at Lorraine were the subject of a 2012, National Instrument 43-101 – Standards of Disclosure for Mineral Projects ("NI 43-101") resource estimate published by Lorraine Copper Corp. titled "Summary Report on the Lorraine-Jajay Property Omineca Mining Division, B.C."¹ with an effective date of December 16, 2015. In that report, Gary Giroux, P.Eng. a qualified person as defined under NI 43-101 provided the following estimate:

A qualified person as defined under NI 43-101 has not completed sufficient work to classify the above historical estimate as a current mineral resource. Sun Metals is not treating the historical estimate as a current mineral resource.

The property is underlain by the Hogem batholith within the Quesnel Trough. The Duckling Creek syenite occurs in the Lorraine area as a multiple-stage dyke swarm emplaced into the older Hogem calc-alkaline intrusive rocks and Takla volcanic rocks. Copper-gold mineralization at Lorraine is associated with the Duckling Creek alkaline magmatism.

The mineralization at Lorraine is typical of alkalic porphyry copper systems characterized by:

• High grades
• Strong gold +/- silver enrichment
• Multiple zones

Some of the highlight results from past drilling at the Lorraine property include:
